Slingshot your shuttle past planets, black holes and spinning asteroid belts to reach the dock. Planets pull you in, but your anti-gravity field can push you away. Time it right.
Drag back from the shuttle and release to launch. Hold ANTI-GRAV (or Space) to repel planets and black holes while you have energy. Asteroid belts start moving when you launch. Earn up to 3 stars per level for speed and low energy use. A new Daily challenge appears every day, and you can save a picture of your neon path when you finish.
Gravity assist: skim past a planet or black hole and swipe (or press WASD / arrows) while the dashed assist ring is up — you gain a speed kick along your swipe, for a little energy. Fuel cells top your energy back up. From level 9 the dock moves, so lead your arrival. Some bodies orbit a centre — their dashed path shows where the gravity well travels.
